Yes I've seen the videos on youtube with the guys with the proper gear....what takes me an hour takes them 20 mins.

If you can spend a grand go a few hundred more, and get a brand new set up, it will pay for itself.

I bought a set up last year and had me money back within 2 months easy, for now it's just another service that's provided for the customers, but I wouldn't be without it

[JandS]

Thinking around £1500 max.

Also look out for like new hardly used kit on fleebay as if your lucky can grab a bargain and save yourself a fortune buying new.

Who needs a washer when hypo does a better job on filthy, black dot & green algae stained slabs 

No dirty overspray blasted everywhere to clean up or mortar removed from between the slabs unlike using a washer

[Smudger]

Now your getting the idea!!

Now your getting the idea!!

Pink dot work trousers are very becoming too

I also cleaned the render walls on that house with hypo to remove the green algae but don't tell anyone. 
Just applyed it by wfp with an old vikan brush dipping into a bucket of the stuff.  Trouble was on the side was part stones and the rest  was filthy concreat on quite a bad slope. By the time I had finish there was a nice trail of cleaned concrete drive where the hypo bucket stood and ran down the drive... Oops! as the lady put it "oh well that's another job for another day you can do then "

Jet washed...hypo and agitate...good rinse off...what's happened....glad it's mine.

Got a before picture ??

The patio was glazed on the surface and the hypo has taken the top layer off 

Good job this is yours and not a customers ! Hypo has its purpose but not for every surface you come across

You sure about that....these are over 10 years old and jet washed about 3 times every year.
Surely the glaze is long gone.

So the last time you cleaned it before without using hypo did it look like that afterwards?

[Aqua Power Solutions]

Glazed as in colour..... Not a polish or sealant
Looking at your before pic .... You are only removing  organic soiling ie algae . No need for hypo

From experience I could use a pressure washer all day long but it still will not totally remove bad algae and black spot staining without causing damage to the substrate.

Hypo is what happened, what strength hypo did you use and at what dilution rate did you use it at. more and more facility managers are banning the use of bleach (sodium hypochlorite) from being used in their facilities both on interior and exterior surfaces. I think finally people are realizing as to why hypo is so detrimental. I also promise i will never again get involved in a post on hypo enough said.  Tadgh

[JandS]

Any remedies or am I going to get it re laid......was thinking about that anyway that's why I wasn't too bothered.
Would prefer a remedy for the time being.

[Smurf]

What strength hypo did you put down and how long did you leave it on for?
Were they as bad as before the last time you cleaned them (seem patchy like that when dry)?
Did you ever put a sealer on those slabs or do you know if you did not get them put down did the prievious owner?

All my time using hypo I've never seen slabs look like that afterwards but I have seen a few very old slabs like that before looking patchy whilst giving quotes and put it down to natural weathering.

Are you sure they are only ten years old as look like they are much older than that?

[JandS]

Hypo at 2:1 water to hypo.
This time they were the worst they have ever been after a Winter.
They could well be older, my brother laid them will ask him and no I haven't put a sealer on them,
